New submission from Bar Harel <[email protected]>:
Continuing with bpo-27589, looks like as_completed documentation is still
misleading. According to the docs, it "Return(s) an iterator of Future objects.
Each Future object returned represents the earliest result from the set of the
remaining awaitables."
There's only one problem: The only thing it definitely doesn't do, is return an
iterator of future objects. To be honest with you, I'm not entirely sure how to
phrase it.
For reference, I fell for this:
mapping = {fut: index for fut, index in enumerate(futures)}
for fut in as_completed(mapping):
mapping[fut] # KeyError
